Actually this was not just an Exhibition card, it was produced to celebrate the World`s Columbian Exposition in 1893, in Chicago, Illinois, the first of all the World`s Fairs, and designed to celebrate the anniversary of Columbus discovering America. The Quaker Oats exhibit was part of a larger group, the American Cereal Company, and there was a special booklet issued, which you can see at the Historic New England Site online.
There are several different adverts found on the reverse of this front, and there are also other cards, two of which which are identical to picture 8 and 10 of the booklet above (the building in the snow, and the ladies packing the oats). This seems to suggest that perhaps the other plates were produced as postcards. So are there any in our collections?
